I just read on the ALGTOP discussion list that Morel has announced a proof of the Friedlander conjecture. Question: Are there other applications besides the Milnor conjecture $H_*(G,F_p)=H_*(BG,F_p)$ for complex algebraic groups $G$? And, for an outsider to algebraic geometry, what is the motivation to consider etale cohomology and how does it relate to ordinary cohomology, i.e. how does Friedlander imply Milnor?
